The view over the city from this blue baroque cathedral is worth the climb to the top of one of the bell-towers. Smolny, once the centre-piece of a convent founded to educate young noblemen and women, is nowadays a concert and exhibition hall with an exhibition of Smolny’s history on display. From the nearby neo-classical Smolny Institute, Lenin orchestrated the October Revolution in 1917. 

Admission 50 - 150Rbl, concerts 200 - 700Rbl. Bell-tower 100Rbl.
